Introduction

Writers have several jobs. Sometimes a writer introduces a new subject.
Sometimes a writer tries to persuade. And sometimes a writer demonstrates
advanced subject matter on a known topic. Occasionally writers entertain, but
seldom do technical writers entertain. It's just too much to ask. (That bit
of sarcasm was my attempt at humor.)

In this article I want to introduce a topic that may be completely new to
you: regular expressions. If you've already heard about regular
expressions, I want to persuade you to consider using this technique. If you
already use regular expressions, I want you to believe that I'm going to
show you an advanced application of regular expressions. And if you just love
technology, you'll be entertained. InformIT is making it possible for you
to be educated, courted, and amusedall in one article.
